Iqhosha lePDC leDTH Drilling

I-DTH yokugrumba yindlela esemgangathweni yoshishino yokomba amatye aqinileyo. DTH =ezantsi emngxunyeni kuba ihamile ihla ngokoqobo- umngxuma. Iibhithi zehamile eziphantsi komngxuma (DTH) zisetyenziswa kunye neehamile eziphantsi komngxuma kwimingxuma yokwemba ngoluhlu olubanzi lweendidi zamatye. I-DTH drill bits ifumaneka ngobukhulu obahlukeneyo kunye nezitayile ezahlukeneyo ukuze bakwazi ukugrumba uluhlu olubanzi lobungakanani bemingxuma.

Ubuchwephesha be-DTH bulula kwaye bukhawuleza ukuziqhelanisa ne-drill ye-directional kwaye ithathwa njengeyona ndlela ilungileyo kunye neyona ndlela isebenzayo yokubhoboza imingxunya ekumgangatho ophezulu njengoko ivelisa ingxolo encinci kunye nokungcangcazela xa kuthelekiswa nezinye iindlela zokomba ezenza ukuba zilungele izixeko. Ingasetyenziswa kuwo omabini amatye aqinileyo nathambileyo kwaye isetyenziswa kakhulu kulwakhiwo, i-oyile negesi, kunye nemizi-mveliso yamanzi.

Isixhobo se-DTH siquka i-hammer drill bit kunye nepiston eqhutywa ngumoya ocinezelweyo. Njengoko i-drill string ijikeleza, i-drill bit ibetha etyeni. I-drill bit ifumana amandla ayo abethayo kwipiston engaphakathi kwehamile eqhutywa ngumoya oxinanisiweyo. Esi senzo kunye nentshukumo ejikelezayo yomtya we-drill ityumza ilitye ngokufanelekileyo. Kuba ipiston ibetha ngokuthe ngqo kwisuntswana, ugqithiso lwamandla lwenzeka phantsi komngxuma kunye nokuphulukana namandla okuncinci, ukuvumela ukugrunjwa kubunzulu obukhulu.

Kwimarike, kukho iibhithi ze-carbide ze-DTH kunye ne-diamond ye-DTH. Xa kuthelekiswa namasuntswana e-DTH e-carbide, amasuntswana e-DTH edayimani anezi zibonelelo zilandelayo:

1. Ubomi benkonzo ye-bit ye-DTH bunyuswe ngamaxesha angaphezu kwama-6;

2. Iindleko zezixhobo zokusebenza zizonke zehle ngaphezu kwe-30%;

3. Ukusebenza kwemveliso yokusebenza kwandiswe ngaphezu kwe-20%;

4. Yenza isicelo ekujoliswe kuso ebekungenakwenzeka ukuba sizaliseke nje ukuba kwenzeke;

5. Ukunciphisa ukuphindaphindeka kokutshintshwa kwesixhobo kunye nokunciphisa ukuqina kwabasebenzi.

Ukuze usebenze ngokufanelekileyo kwi-Down-The-Hole (DTH), udinga izixhobo eziphezulu zokuqhuba, ezonyusa imveliso yakho kunye nokuzinza, ngelixa unciphisa iindleko zakho zokusebenza kunye nokukhutshwa.

Ngaphakathi kwe-ZZBETTER, sinikezela ngamaqhosha e-PDC kwi-DTH drill bits, ukwandisa iziphumo zakho kunye nokuphucula amava akho okuqhuba. Iindidi zethu zabasiki bePDC zenziwa kusetyenziswa izixhobo ezikumgangatho ophezulu ukukubonelela ngolungelelwaniso oluhle phakathi kokungena kunye nobomi bebit. Sinikezela ngoluhlu olubanzi lwemigangatho kunye neyenziwe-uku-odola abasiki bePDC kukhetho olubanzi lweesayizi ezinoluhlu olubanzi loyilo lokumila ukuze lulungele yonke iprojekthi.

Ukuba unomdla kwi PDC cutters kwaye ufuna ulwazi oluthe vetshe kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
